DeepSeek V4.1 Pro status: one official mention, no date, no id, no price
One mention, no date, id or price
As of 2026-10-07, DeepSeek V4.1 Pro has not been released: the official changelog, news page and pricing page give no date, model id or price for it. “V4.1-Pro” appears only once, in the 2026-09-10 V4.1 Flash release note, in a sentence saying deepseek-v4-pro requests will route to V4.1-Flash until V4.1-Pro launches; the changelog entry of the same day says V4 Pro API service continues after 2026-09-14 with the billing method unchanged. Today on QCode you set deepseek-v4-pro or deepseek-v4.1-flash (DeepSeek's own id for that tier is deepseek-flash).

What official docs actually say
Official launch date
As of 2026-10-07, the release note, changelog and pricing page all give no date for V4.1-Pro.
Official model id
Neither /models nor the pricing table lists an id for V4.1-Pro.
Official mention
"This will continue until V4.1-Pro launches", in the 2026-09-10 release note.
Premise of that line
It describes how long deepseek-v4-pro requests route to V4.1-Flash; the same-day changelog entry says V4 Pro continues after 2026-09-14 with the billing method unchanged. As of 2026-10-07 both lines are still on the official pages.
What this is
The 2026-09-10 V4.1 Flash release note says: “Starting at 04:00 UTC on Sept 14, 2026, all deepseek-v4-pro requests will route to V4.1-Flash at V4.1-Flash rates. This will continue until V4.1-Pro launches.” The changelog's 2026-09-10 entry says: “we have decided to continue providing API services for DeepSeek V4 Pro after September 14, 2026, with the billing method remaining unchanged.” As of 2026-10-07 both pages still carry these sentences; the pricing page still lists deepseek-v4-pro (version DeepSeek-V4-Pro-0813), and the only note attached to a model row there is footnote (1) on deepseek-flash. V4.1-Pro itself still has no date, id or price.
What happened
The 2026-09-10 release note says "This will continue until V4.1-Pro launches". The changelog's 2026-09-10 entry says V4 Pro API service continues after 2026-09-14 with the billing method unchanged. As of 2026-10-07 both lines remain on the official pages; this page does not judge which one is in effect.
Timeline
2026-08-13 DeepSeek-V4-Pro-0813 went GA — the only Pro id you can set today.
2026-09-10 the V4.1 Flash release note names V4.1-Pro once: "This will continue until V4.1-Pro launches".
The release note says all deepseek-v4-pro requests route to V4.1-Flash starting 04:00 UTC on 2026-09-14; the changelog's 2026-09-10 entry says V4 Pro continues after 2026-09-14 with billing unchanged. Both lines stand.
Confirmed vs caution
Officially confirmed
The pricing page confirms the two live ids and version names; the changelog's 2026-09-10 entry confirms v4-pro continues after 2026-09-14 with billing unchanged.
⚠️ Caution
"V4.1 Pro is imminent" is a reading of that one sentence taken out of context. The sentence is about how long deepseek-v4-pro requests route to V4.1-Flash, while the same-day changelog entry states V4 Pro continues after 2026-09-14 with the billing method unchanged — the two lines stand side by side, and there is no official date, id or price. This page carries no schedule speculation.
Same vs differs
Same
Where all three official documents agree: the live ids are deepseek-flash and deepseek-v4-pro, versions DeepSeek-V4.1-Flash and DeepSeek-V4-Pro-0813 (on QCode, the V4.1 Flash tier is called deepseek-v4.1-flash).
Differs
Only the release note mentions V4.1-Pro, once, in a line about how long the v4-pro rerouting lasts, while the same-day changelog entry says V4 Pro continues after 2026-09-14 with billing unchanged; the changelog and pricing page never mention V4.1-Pro.
What to do
If you are waiting for V4.1 Pro: there is no date, id or price to align to, so keep it out of release plans and customer quotes. For the Pro tier today set deepseek-v4-pro (version DeepSeek-V4-Pro-0813) on QCode; for the newly released tier set deepseek-v4.1-flash (DeepSeek's own id is deepseek-flash).
On QCode
QCode sells deepseek-v4-pro (real 30-day traffic) and deepseek-v4.1-flash. V4.1 Pro is unreleased officially, so no id exists to add; availability follows /models.
FAQ
Is V4.1 Pro an official name?
It is a model name DeepSeek wrote once in the 2026-09-10 release note. As of 2026-10-07 there is no official source outside that sentence, and no id, date or price.
When does it launch?
Officially unstated as of 2026-10-07. None of the three documents gives a date, so any specific date you see is not official.
How does it relate to deepseek-v4-pro?
The official sentence actually tied them together: the release note said deepseek-v4-pro requests would route to V4.1-Flash until V4.1-Pro launches. The same-day changelog entry says V4 Pro API service continues after 2026-09-14 with the billing method unchanged, and as of 2026-10-07 the pricing page still lists the Pro tier as deepseek-v4-pro (DeepSeek-V4-Pro-0813). Both lines stand side by side, so this page draws no conclusion about how the two relate.
Does "until V4.1-Pro launches" still hold?
As of 2026-10-07 the sentence is still in the release note, but the same-day changelog entry says V4 Pro continues after 2026-09-14 with the billing method unchanged; both stand side by side, and this page does not judge which one is in effect. The note says all deepseek-v4-pro requests will route to V4.1-Flash from 2026-09-14 04:00 UTC and adds "This will continue until V4.1-Pro launches" — so "This" refers to the v4-pro rerouting. It therefore supports neither "V4.1 Pro is imminent" nor any deadline for the legacy flash-id routing.
Which id should I set?
For Pro, deepseek-v4-pro. For the tier released on 2026-09-10, deepseek-flash officially — deepseek-v4.1-flash on QCode. Always defer to /models.
How fresh is this page?
Conclusions were last checked on 2026-10-07 (first checked 2026-09-18). As soon as DeepSeek publishes a V4.1 Pro id or date, this page goes stale and needs a re-check.

This page separates three tiers: what official docs confirm about the live ids, the rumour and circulating schedule claims, and what stays unconfirmed — no official id, date or price. Beyond one passing mention, V4.1-Pro has no official information, so no capability claims and no leaked benchmarks. Last checked 2026-10-07; official pages take precedence, and model availability is as listed on /models.
